Microwave rotational spectra and structures of 2-fluoropyridine and 3-fluoropyridine.
TL;DR: The experimental results are consistent with a bonding model that involves hyperconjugation whereby fluorine donates electron density from its lone pair into the π-system of pyridine.

Investigation of structural trends in difluoropyridine rings using chirped-pulse Fourier transform microwave spectroscopy and ab initio calculations
TL;DR: The ground state rotational spectra of 2,3-, 2,4, 2,5-, 2.6-and 3,5-difluoropyridine have been investigated using both Balle-Flygare type Fourier transform microwave (FTMW) and chirped pulse Fourier Transform Microwave (CP-FTMW), and the results were consistent with the MP2 (6-311G++2d2p) level of theory as mentioned in this paper.

Investigation of Structural Trends in Mono-, Di-, and Pentafluorobenzonitriles Using Fourier Transform Microwave Spectroscopy
TL;DR: The spectroscopic analysis allowed the derivation of substitution and effective ground state structures to investigate the effect of mono-, di-, and pentafluoro substitution on the geometry of the BN backbone and are compared with ab initio values of the equilibrium parameters obtained from MP2/6-311++G(2d,2p) calculations.

Rotational spectra and structures of the van der Waals dimers of argon with 2-fluoropyridine and 3-fluoropyridine.
TL;DR: The rotational constants and (14)N nuclear quadrupole coupling constants derived from fitting the observed transitions were used to estimate the van der Waals coordinates of the two complexes.
Microwave spectroscopic investigation and structural determination of the Ar-difluoropyridine van der Waals complexes.
TL;DR: The spectroscopic parameters derived from fitting the observed transitions were used to estimate the van der Waals coordinates of the five weakly bound complexes and to quantitatively describe their internal dynamics using a pseudodiatomic model.
